The AMT says commuter rail service will resume on its Candiac line, in time for Thursday morning's rush hour.
Train service was cancelled Tuesday night and all day Wednesday because of ongoing protests against the Dakota Access Pipeline project.
Mohawk activists in Kahnawake gathered early Tuesday along Highway 132 as part of a show of solidarity with the Standing Rock Sioux Tribe reservation, whose members have been clashing with police and private security during protests over the controversial pipeline project in North Dakota.
Commuters who rely on the train were forced to board shuttle buses to transport them from downtown to the communities of Delson, Candiac, Saint Constant and Sainte Catherine during the blockade.
